Why Do I Need to Degrease Before I Blast?
IS DEGREASING REALLY THAT IMPORTANT?
Yes, Preparation is everything and it’s very important that your parts are thoroughly degreased before application. Oils and other contaminants get trapped in tight areas and are released via heat through the gas out phase or curing phase. Improper degreasing will compromise adhesion in those areas and cause delamination of coating. For optimal adhesion it is imperative that the substrate be free of any contaminates i.e. oils, dust, grease, media. Degreasing also helps preserve your sandblast media by removing the grease and oils on your parts prior to blasting. This reduces contamination when sandblasting future projects.
